I checked and run again the preprocessing of one image and I still have c1c* c2c* c3c* c4c* c5c files and for the tissues 1 2  4 and 5 I don't have the c1* c2* and c4* and c5* files . What are these files? It doesn't look like I do twice the same preprocessing steps because I checked and I just used the default preprocessing pipeline (see attached screenshot). For tissue 3, I have much more output files (y_c3_*, iy_c3*.nii , *seg8.mat and so on) that for the other tissues I don't have. What is the problem?

Could you help me out?

Thank you,

Marianna
